This invention relates to window constructions and particularly tometallic windows of the swinging sash type.

Many types of windows of the swinging 5 sash type have heretofore beendesigned or suggested and many thousands have been manufactured'and putinto use. Recently metallic windows have been extensively manufactured,asit hasbeen found that windows of this typepresentnumerous advantagesover windows ofthe prior type, con-. structed of wooden members. Thepresent invention, while'particularly directed to improvements-inmetallic. window constructions, may nevertheless be embodied in woodenwindow constructions, as will be apparent to one skilled in the art.

The objectof the invention-is to provide a window comprising a frame andsash, in -1 which the sash maybe moved from closed to open position,orcompletely removed from the frame with great ease, and which is at thesame time very simple inconstruction, may be easily fabricated, and isattractive in appearance.v The invention may be embodied in windowswhich vary widely in physical appearance, not being limited in itsusefulness to any particular type, and is very well adapted forembodiment in the well-known 3? form of square or rectangular windowcommonly used for lighting and'ventilating basements. In theaccompanying'drawings two such basement windows are illustrated, both ofthese windows being of the same general 3? type but differing somewhatin details of construction, these' windows being" set. forth merely byway of' example, as the invention may be embodied in numerous additionalspecific forms of window constructions dei signed to suit variousrequirements of builders," designers and'architects.

The improved window illustrated in Figures 1 to 8 inclusive comprisesessentially a frame, generally indicated at 10 and a sash, generallyindicated at 11. The frame, in the embodiment selected for purposes ofdisclosure, is rectangular, and is preferably formed of T bars rigidlysecured together at the corners'as by welding. The two vertical T bars12 and 13 present their flanges to the front of the window, with websrearwardly directed as does the upper horizontal member 14 of the frame.The lower horizontal member,15 also comprises a Thai but its flangedhead is presented'rearwardly and its web extends toward the front'of thewinow. As viewed in vertical section therefore, as for instance inFigures 3 and 4, the upper and lower framcT bars 14 and 15 are reversed.

The sash 11 comprises four similarly shaped angle members 16 rigidlysecured together toform a rectangular frame. Vertical T bars 17 connectthe upper and lower angle member 16 ofthe sash at intermediate points'and thus divide the area of the sash into three equal spaces. The glassplates comprising the window panes are indicated at 18 and these platesare secured in position by securing devices hereinafter to be fullydescribed. Between the margins of Bach plate or pane of glass and themeta lic I w 21 of the arms 21.

member in front of the same are located strips of cork or the like,indicated at 20, which cushion the glass or provide a shock absorbingmedium intermediate the glass and the supporting members of the sash,thus minmizing rattling and breakage. Preferably these cushioning layersare of cork and are glued to the metal frame members of the sash.

The vertical side members of they sash are spaced somewhat from the websof the vertical side members 12 and 13 of the frame, as will beapparent'upon an inspection of Figure 2 and in the spaces between'theparallel side members of the frame and sash are positioned theswinging'arms 21,21, which are pivoted at their upper ends, as at 22, 22to the vertical frame members, the pivots 22, '22 being in the samehorizontal plane and aligned with each other so that arms 21, in effect,swing about a common horizontal axis. Each arm 21 is provided at itsbottom with a projection 21 which extends rearwardly of the frame andeach such rearward projection 21' has a laterally inturned extension 21at its end which lies in the path of movement of the adjacent sash sidemember if the sash be rocked rearwardly upon its lower edge.

Each vertical side member of the sash is notched at 23, the notchesbeing formed by striking up from the side members lateral projections24. The notches are adapted to receive, respectively, the lateralprojections Pivotally secured at 25 to the top horizontal member of thesash is a latching lever 26 having a' handle portion 27 and acatch-engaging portion 28.. The catch-engaging portion is adapted toengage, when swung about its pivot 25, a catch 29 struck downwardly fromthe upper horizontal frame member 14. The latching device just describedis described in detail in my Patent 1,706,100 granted March 29, 1929. r7

In Figure 3 thesash is shown in closed position and it will be apparentthatthe outer margin of its front face tightly engages a flat rearwardlyfacing cooperating surface of the frame. This makes agood weatheringcontact around the top and sides of the frame. At the bottom thehorizontal portionof the bottom sash member simply rests uponthe web ofthe bottom frame member 15. The sash is locked against inward movementby thelatching device 27 at its top and the flange of the T bar 15 atthe bottom. 7 i To open the window it is first nec'essary to release thelatching device by swinging it aroundthe pivot 25 so that portion 28 disengages catch '29. The windowc'an then be tilted to dotted line positionA in Figure 4,, atwhich time the notches 23- in the side members ofthefsa'sh will engage the lateral projections 21 of arms 21. By pullingupon the latch, or top bar of the sash, the sash may be further rotatedabout a horizontal axis which includes the upper edges of lateralprojections 21 into the position in which it is shown in full lines inFigure 4. In this position the lower forward corner of the sashfrictionallyengages at its ends the rearwardly facing surfaces of theflanges of the side frame members 12 and 13. The window will befrictionally retained in this position. It may be easily lowered orcompletely removed. To remove the same it is only necessary to lift theupper end of the sash through a short distance or until projections 21are disengaged from notches 23. After such disengagement the sashmay bereadily lifted from the frame and taken to anydesired point. Infabricating the window the distance between the upper edge of theprojection 21 and the pivotal axis 22 is made less than the distancebetween notch 23 and the bottom of the swinging sash. That being so,it'is possible only to swing the sash 16 through 0. limited angle aroundits pivotal axis located in the notches 23 iii-opening the same andhence there is no danger of thesash tilting backwards and beingdisengaged by members 21', and falling. In Figure 4 the sash is shown'(position B) to be tilted very nearly as far is is possible for theconstruction shown.

The sash supporting arms may be so dc signed that they do not disengagethe notches in the sash when the sash is closed. A construction of thiskind is shown in Figures 9 10 andll. Here the lateral projections 40 ofarms 40 lie in notches 41' of sash 41 at all times, except when the sashis completely re moved from 7 the frame. In this case the notches-may beso positioned that the lower angle bar of the sashis slightly spacedfrom the lower frame member when the sash is in closed position. Thenotch '41 may be shaped in various ways, with the end in view ofbringing" about a movement in opening which is identical with that ofthe form first described.

It willbe noted that the projections 40' of arms 40 he intermediate thefront and rear edges of the frame members, when the sash is in closedposition (Fig. 10). jections are therefore protected by theframe fromdamage during-shipment. If desired the projections 21 of the form of theinven tion shown in Figures 1 to 8 inclusive may be caused to lieintermediate the front and rear edges of the frame members, for the samepur ose.

It will be noted that, with both forms of the window disclosed, thevertical sash members have small portionsthereof laterally, deflected tooverlie the adjacent swinging arm. Thus the projections 16, of the sashshown in Figures 1 to 8 inclusive, overlie the swinging arms 21, and thelateral projections 41" of the sash members 41 of the form of the Theseproinvention shown in Figures 9, 10 and 11 overlie the swinging arms 40.These projections have an important function i. e. they contact with,and return to their pendent vertical positions, the swinging arms, asthe sash is moved to closed position, should these arms have a tendencyto stick, or remain in the positions which they occupy when the sash isopen.

The means for holding the, panes of glass in position is shown inFigures 6, 7 and 8. Plugs or pins such as 42 are passed through the websof the vertical T bars of the sash, at top and bottom, and lugs such asindicated at 43 are struck in from the webs of the vertical .angle barscomprising the side members of the sash, these lugs being in the samehorizontal planes as the cooperating pins 42. Flat resilient springmembers 44 have their ends positioned inside of the pins and lugs andtheir central portions in contact with theglass. The action of springs44 presses the pane of glass tightly against the cork facings 20 and theglasses are thus tightly held in position. 7

It will be understood that, while I prefer to form both the frame andsash of metallic shapes, preferably of angle bars and T bars, theinvention is not limited to any particular type or form of frame andsash members. Other structural metallic shapes may be employed ifdesired or wood strips utilized if preferred for any reason.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

l. A window construction comprising in combination, a frame having avertically disposed seating surface for a movable sash, a sash themargin of which is adapted to bear against said seating surface when inclosed position, and means on the frame for supporting the sash when itis moved to open position, said means wholly disengaging the sash whenthe sash is in closed position.
